Water- and metal-rich atmospheres on compact hot mini-Neptunes lose mass more slowly than H/He cases at high enrichment levels due to enhanced cooling and higher mean molecular weight.
Varying the adiabatic index from 1.2 to 1.4 in exoplanet evolution models shows that higher gamma produces puffier initial envelopes that contract faster with accelerated mass loss, so using gamma=1.4 overestimates mass-loss effects on young planets.

The Effect of Adiabatic Index on Radius Evolution and the Mass Loss
Varying the adiabatic index from 1.2 to 1.4 in exoplanet evolution models shows that higher gamma produces puffier initial envelopes that contract faster with accelerated mass loss, so using gamma=1.4 overestimates mass-loss effects on young planets.
